Abstract

The objective of this study was the evaluation of root micorrhyzal colonization and the spore density of arbuscular mycorrhizal fungi (AMF), as well as the effects of tillage systems in two soil classes (Entisol and Oxisol). The study was carried out in farms around the ";Parque Nacional das Emas";, Goiás State, Brazil, where density of AMF spores and mycorrhizal colonization of roots in the different tillage systems were determined. Areas cultivated with grasses presented larger mycorrhizal colonization and density of AMF spores in both soils as compared with the soybean cropped area. Small effect of the tillage systems was verified in regard to evaluated characteristics. However, the results showed alterations in the AMF population, with an increase in spore density, that was reflected in the mycorrhizal colonization in the cropped areas as related to the reference areas.

KEY-WORDS: Biological indicator; sandy soils; conservation of the soil; soil quality.
